Talk:Monte Carlo N-Particle Transport Code

History

I wonder if the code has a long history. It might be based on codes written for the first generation of computers used in Los Alamos. 128.6.168.245 (talk) 17:14, 18 November 2008 (UTC)

The code base was originally started in the 1940s with Enrico Fermi, Nicholas Metropolis, Robert_D._Richtmyer, John von Neumann, and Stanislaw Ulam. The first version was just plain machine code. The machine code was eventually organized into MCA and MCS, which was later combined into MCN. MCG was eventually merged into MCN and MCNG was born. In the late 1960s and early 1970s, MCP and KCODE were merged in to form MCNP. MCPLOT and MCMG were then merged into MCNP. Finally, roughly back in 2000, MCNPE was merged into MCNP to form the modern day MCNP5. 174.56.49.228 (talk) 04:31, 14 February 2011 (UTC)

Take a look at [1]. It would appear that the original version of the MCNP codebase ran on Metropolis' MANIAC. fintler (talk) 15:27, 14 February 2011 (UTC)

Computer Science Topic

I just added the "needs attention from computer science" because it seems like this program may have some deep roots in the history of computer science. Especially when you consider that Nicholas Metropolis' MANIAC I, John von Neumann, and Stanislaw Ulam was probably involved in its creation. fintler (talk) 15:34, 14 February 2011 (UTC)

Potential Qualified Attention

I am a Nuclear Engineering PhD student at Rensselaer Polytechnic Institute. I use this code regularly, I have attended seminars given by one if its developers, and I plan to update this page at some point when I have the chance. Vazquez88 (talk) 06:44, 16 May 2011 (UTC)
